Fatigue resistance of inclined hangers in a suspension bridge to traffic loads is evaluated. First, it is confirmed that stress ranges and frequencies calculated by the simulation analysis are in good agreement with those measured on a bridge. The stress ranges and frequencies of inclined hangers are estimated by this simulation analysis.
Second, design S-N curves of the parallel wire strand cables are obtained by an approach based on the statistical theory of extremes and fatigue tests. The cumulative damages of inclined hangers are calculated by applying both Miner's rule and the results obtained.
